Prisoner kills inmate who beat infant daughter to death

Authorities said a man serving a life sentence for murdering his two-day-old baby was found dead in his U.K. prison cell over the weekend.

Liam Deane, 22, who was jailed in October for punching, shaking and squeezing his baby girl to death after she wouldn't stop crying, was found dead in his cell at HM Prison Leeds in England on Sunday, The Yorkshire Evening Post reported.

Deane admitted to murdering his daughter, Luna, while her mother was sleeping in their family home in Wakefield, England, last July.

He reportedly lost his temper during the night he subjected his daughter to a brutal attack. The baby died in intensive care after suffering "catastrophic brain injuries" from her father.

As a result, Deane was sentenced to life in prison and could have served a minimum of 10 years.

Another inmate, John Westland, 28, was charged with Deane's murder in court on Tuesday and is being held in custody. It remains unclear why Westland was originally admitted to jail.
